 =====  =====
 The DISPLAY command controls fScan's interactive display properties.
+  * DEV - The DEV argument can be any recognized X host; default is local display.
-  * DEV - The DEV argument can be any recognized X host, either by IP address or name (e.g. myhost, or myhost.biac.duke.edu, or 152.3.98.222).
+    *  Examples:  myhost, myhost.biac.duke.edu, 152.3.98.222
-  * FLG - The FLG argument is a bit flag with the following meanings:\\
+  * FLG - The FLG argument is a bit flag with the following meanings:
-    * 1 - display results progressively; otherwise calculate all then display
+    * 1 - show only one window at a time (<enter> or 'j' to switch)
-    * 2 - show only one window at a time (<enter> or 'j' to switch)
+    * 2 - onscreen (overrides default OFFSCREEN setting when displaying across a network)
-    * 4 - offscreen
+    * 4 - offscreen -- render 3D graphics to buffer, then transfer to display (default for networked display)
     * 010 - open all data windows initially (default is to only open if < 10 data sets)
     * 020 - only display main interactive menu
     * 040 - don't display any interactive menus
     * 0100 - don't display window text
+    * 0200 - don't display any windows (for running scripts with embedded interactive commands)
+    * 01000 - turn windows on/off to raise to front (use if window manager does not raise windows properly)
+    * 02000 - flip RGB bytes when creating JPG images
-  * PANELS - PANELS can be used to specify how many rows to use for showing images; the default is to arrange panels in multiple rows (obsolete -- use '-set showpanes').
+  * PANELS - PANELS can be used to specify how many rows to use for showing images; the default is to arrange panels in multiple rows (see also '-set showpanes').
-  * TNAM - TNAM is a character string to use as a filename prefix when creating TIFF files. The normal filename can be overridden when creating TIFF files interactively. The default prefix is the source file name (INFILE).  Obsolete -- use '-set tiffname'.
+  * ZOOM - Zoom factor to be applied to all windows (see also '-set showzoom').
-  * NCOL - NCOL can be used to specify the number of palette colors to use.
+    * ZOOM 0 - no zooming
-  * HDRTXT - HDRTXT is a text string that will be displayed in each window (obsolete -- use '-set showtext')
+    * ZOOM 1 - zoom by 3/2
-  * SCAL - SCAL is the initial intensity scaling factor to be applied to all windows; the default is 0.0, which results in autoscaling (obsolete -- use '-set allscale')
+    * ZOOM -1 - zoom by 2/3
+    * ZOOM > 1 - zoom by ZOOM factor
+    * ZOOM < -1 - zoom by 1/ZOOM factor
+  * TNAM - TNAM is a character string to use as a filename prefix when creating TIFF files. The normal filename can be overridden when creating TIFF files interactively. The default prefix is the source file name (INFILE).  (See also '-set tiffname').
+  * NCOL - NCOL can be used to specify the number of palette colors to use (partially implemented).
+  * HDRTXT - HDRTXT is a text string that will be displayed in each window (see also '-set showtext')
+  * SCAL - SCAL is the initial intensity scaling factor to be applied to all windows; the default is 0.0, which results in autoscaling (see also '-set allscale')
